Charlie equalized the guest wife helping in the kitchen with the guest “husbands” helping in the kitchen. His intention was egalitarianism (as he makes clear in his voluminous posting history). That is anathema to Jewish values.
It’s not an anathema. It’s proper derech eretz. Maybe it’s written in your ketuba that the kitchen is your wife’s quarters and job, but it’s not written in our ketuba . . . and I doube it’s written in anyone elses, either.
